The aim of this investigation is focused on the evaluation distinctive coatings commonly applied in automotive industry. resulting corrosion behavior analyzed by using electrochemical impedance spectroscopy (EIS), equivalent circuit (EC) and potentiodynamic polarization curves. novelty concerns a comparison between tricationic phosphate (TCP), cataphoretic electrodeposition (CED) an epoxy layer...

Abstract The coiling stable roll of hot-dip galvanized is a defect formed in the galvanizing process. zinc slags and floating foreign matters pot will directly or indirectly adhere to surface stabilizer with flow liquid. When strip steel contacts roll, slag extrude deform iron base plate form pits. In this paper. causes defects were analyzed. There two methods eliminate that is, reduce generati...

Abstract The paper shows a significant influence of the multi-stage wire drawing technology on deformability and phase transformations in zinc coating. SEM tests proved that coating after hot-dip galvanizing consists number thin layers, ranging from 1 to 5 µm, differing thickness, chemical composition properties. When pulled through die heats up (as result friction between material tool) its dy...
